Line Maze Robot is a machine that can follow a path, the paths are lines. The color of the lines are black and the ground is white. So, at first, the robot must have an ability to follow the lines. Lines are 2cm width. Of course there will be + and T intersections in the maze. The problem is to solve these intersections and to overcome any unexpected blocks in the path. There may also a problem of the robot selecting the same path every time, and this might cause the robot not to find the exit, along with this if the robot has to climb or get down on the stair case it might be difficult for it to follow the path. This has been a challenge for us. So some hardware and algorithms have been designed and developed to overcome this difficulty.

INTRODUCTION
Let us begin with one key observation: cars are cool. From consumer transportation to manufacturing facilities, vehicles in their many forms are some of today’s most influential machines. Autonomous vehicles are already in use in many manufacturing facilities. Perhaps one day, the world’s highways will be filled with cars requiring no user intervention. While we are not there yet, an autonomous vehicle can serve as very interesting and practical design exercise.
As a programmer we get an opportunity to ‘teach’ the robot how to follow the line thus giving it a human-like property of responding to stimuli. Some of the practical applications of a line maze robot are automated cars running on roads with embedded magnets, guidance system for industrial robots moving on shop floor etc.,
